SPECIFICATION formingpart of Letters PatentNo. 728,064,"Clated May 12, 1903. Application filed December 26,1902. Serial No. 136,679; (No model) T at whom it may concern:

Be it known that I, JAMES A. WORKMAN, Sr., a citizen of the United States, residing at Portageville, in the county of New Madrid and State of Missouri, have invented new and useful Improvements in Pump-Motors, of which the following is a specification.

My invention relates to pump-motors; and the object of the same is to construct a device of this character which can be operated either by hand, gravity, or other power to drive a double-pitcher pump.

The simple and novel construction employed by me in carrying outv myinvention is fully described and claimed in this specification and illustrated in the accompanying drawings, forming a part thereof, in which Figure 1 is a front elevation of my motor. Fig. 1 is a detail of the locking-sleeve. Fig. 2 is a similar view from the rear. Fig. 3 is a detail elevation of the pinion and ratchet. Fig. 4 is a side elevation of the same. Fig.

5 is a section on the line 5 5, Fig. 2, with the pawls removed.

Like numerals of reference designate like parts in the different views of the drawings.

pawl 8 and havinga gear 9 rigidly connected- Two-shaftslO are mounted'one on thereto. each side of the shaft 4 and parallel thereto, and keyed on each of the shafts 10 is a flan ged drum 11, carrying a gear 12, meshing with:

the gear 9. The drums 11 are designed for for driving my motor. The ropes 13 extend I up and around sheaves 15, bearing spindles journaled in the slotted'ends of a cross-bar 16, supported by the uprights 6. The ropes 13 are wound in opposite directions on the drums 11, so that in their descent both the weights 14 will drive the pinion 1 in the same direction-a clockwise directionwhen the pawl 8 has been thrown out of engagement with the ratchet.

To operate the shaft 4 and drums 11 to wind up the weights 14, a sprocket 17 is fixed on the end of'the shaft 4 in alinement with a sprocket 18, fixed on a shaft 19, journaled in cross-bars 20 and bearing a crank 21, provided with a handle 22 for use in operating the shaft 19. A sprocketchain 23 passes over the sprockets 17 and 18 and enables the weights 14 to be raised by turning'the crank 21, after which the pawl 8 will hold them against descent.

The means for transmitting the motion of the pinion 1 to a horizontal pump 24 will now .be described. v p

A lever 25 is fulcrumed intermediate its ends on a pin 26, seated in the frame, which lever has oppositely-extending arms 27 and 28. The upwardly-extending arm 27 is beveled oft'at 27 to a chisel edge and is located to be engaged by the teeth 2 and swung through an angle of about sixty degrees. A

.lever 29 is fnlcrumed at its lower end on a pin 30 and extends upwardly in position to be engaged by the teeth 2 on the pinion 1 after they have cleared the upper end of the arm 27 A link-bar 31 is' pivoted at one end to the lever 22 above its fulcrum and to the lower arm 28 of the lever. 25 below its fulcrum 26. By the link 31 the levers 25 and 29 are constrained to move in unison and in opposite directions. The forward movement of the lever 29 carries the lever 25 back to its initial position. The lower arm 28 of the lever 25 is jointed at 32, and a sleeve 33 nomally fits over this joint to hold the arm 28 rigid, except during the operation of raising the weights 14, when the sleeve-33is moved from over the joint to permit the joint to bend and the rotation of the pinionto be reversed without deranging the lever mechanism.

Pivoted to the lower end of the arms 28-of a link 85, which is also pivoted to a horizontal connecting-rod 36, pivot-ally connected to the upper arms 37 of two pumping-levers 38,-, fulcru med intermediate their ends, and the lower ends of which are connected to links 39, also connected to piston-rods 40, carrying pistons 41, fitting pump-barrels 24.

The outer end of one of the shafts 10 is traversed by a thread 42, at the end of which is located a lug 43. A pivoted catch 44, having a sharp nose 44,is mounted with the nose engaging the groove between the thread 42. This device is what Icall aset-stop, for as the shaft 10 revolves the catch 40 will follow the thread 42 until it comes in contact with the lug 43, which will bring the shaft 10 to a stop, and therefore the Weight 14 and pump 24. The time necessary for the catch 44 to traverse the thread 42 is just sufficient to permit the weight to run down. A second stop, which is termed a bucket-stop, which stops it the pump when a bucket of standard size is filled, is also provided. This bucket-stop comprises a ratchet 45, keyed on the shaft 4 and having but one tooth 46 thereon, which is located to be engaged by a pawl 47. By this arrangement the shaft 4 is free to turn through a complete revolution before being stopped by the pawl 47.

The operation of my motor can now be described. Suppose the initial position oi the parts to be that shown in Fig. 1, with the Weights 14 wound up. To pump water, the pawl 8 is thrown out of engagement with the ratchet 7, releasing it. The weights 14 will then descend, thereby unwinding the ropes 13 from the drums 11, rotating them and the gears 12, which in turn rotate the gears 9 to drive the pinion 1. As the pinion 1 revolves the teeth 2 will in turn engage the arm 27 of the lever and swing it through an arc of about sixty degrees, when it will clear this arm and engage the lever 29 andswingit through an arc of equal length; but the swinging of the lever 29 will actuate the link 31, which will operate the arm 28 to restore the lever 25 to its initial position, when it will be engaged by the next tooth 2 and the operation repeated. The teeth 2 are so spaced that the levers 25 and 29 are never both engaged by the teeth 2 at the same time. The swinging of the lever 25 will actuate the connecting-rod 36 and operate the pumping-levers 38 to reciprocate the pistons 41 in unison to pump water. When it is desired to stop the pumping, the pawl 8 is thrown into engagement with the ratchet 7 after bringing the weights 14 to a stop by pulling upon the ropes 13. After the weights 14 have run down the sleeve 83 is moved 0% of the joint 32 and the crank 21 turned by hand to drive the sprockets 17 and 18 to turn.

the pinion 18 backward and operate the drums 11 to wind up the ropes 13.

I do not wish to be limited as to details of construction, as these may be modified in many particulars without departing from the spirit of my invention.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is

1. In a pump-motor, the combination of a pinion provided with teeth separated byconsiderable intervals, means for driving said pinion, a lever fulerumed intermediate its ends and set with the end of its upper arm in position to be engaged by the teeth on said pinion, a lever fulerumed on its lower end and extending up in position to be engaged by said teeth after clearing said first-mentioned lever, and a link-bar pivoted to the lower arm of said first-mentioned lever and to said last-mentioned leverintermediate the ends of said lever, substantially as described.

2. In a pump-motor, the combination of a pinion provided with spaced teeth, means for driving said pinion, a lever fulcrumed intermediate its ends and mounted with its upper arm in position to be engaged by the teeth of said pinion to swing said lever in one direction, a lever fulcrumed at its lower end and located to be engaged by said teeth. to swing it in one direction, a rigid link-bar pivoted at one end to said last-mentioned lever and at its other end to the lower arm of said firstmentioned lever, whereby said levers are operated to swing in unison and in opposite directions, substantially as described.

3. In a pump-motor, the combination of a revolving shaft bearing a coarse thread, a pivoted catch having a sharp nose engaging said thread, a stop located at one end of said thread whereby said catch is engaged and said motor stopped, and means for driving said shaft, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
